The invention solves the problems that the loss prevention scheme of the existing self-service cash register system has too much manual intervention, the anti-theft tags and commodities cannot be identified in a one-to-one correspondence manner, manpower and cost are consumed, and loss prevention is difficult to realize better.
Description
Technical Field
The invention relates to the technical field of self-service cash register loss prevention, in particular to a self-service cash register AI loss prevention system and method based on hand track recognition.
Background
Self-service cash collection is originally appeared in large supermarkets of developed countries such as Europe and America, and is popular among customers in a convenient and quick self-service mode. At present, self-service cash register walks into China and is gradually used in shopping malls, supermarkets and convenience stores in a plurality of cities, on one hand, the form of self-service cash register is more convenient and faster, and customers can finish operation by themselves through man-machine interaction, so that much time for queuing and closing is saved, the efficiency is improved, and the shopping experience of the customers is improved; on the other hand, the self-service cash register equipment is installed, so that the labor cost is saved for the merchant, and considerable benefits are brought.
Although the self-service cashier solves the pain points that the manual cashier experience of the retail industry is poor, the labor cost is increased and the customer queues up in shopping, the loss prevention problem concerned by the retail enterprise is not well solved, and the loss prevention solution for the self-service cashier is probably as follows:
1. weighing and loss prevention: the customer scans the commodity and puts the commodity on the loss prevention electronic scale, reaches the purpose of loss prevention through comparing commodity weight, and the loss prevention of some ordinary commodity can be solved to this scheme, but the shortcoming that exists is: sales promotion is frequent in the operating process of a market, frequent binding sales promotion, fresh processing and the like are carried out, the weight of commodities is changed greatly and is not fixed, the comparison of the weight of the commodities is wrong, manual assistance is needed, and customers may need to ask for help frequently in one transaction, so that too much money is paid in advance and the experience is poor in the self-service cash receiving process;
2. anti-theft label loss prevention: the anti-theft label commonly used in the supermarket at present is of acoustic magnetic type and radio frequency type, the commodity with the anti-theft label can be demagnetized when passing through the demagnetizer, a plurality of commodities can be demagnetized simultaneously when approaching, and the existing defects are as follows: the anti-theft label and the commodity do not have a one-to-one correspondence, so that the purpose of effective loss prevention cannot be achieved during self-service cash collection;
3. radio frequency identification loss prevention: radio Frequency Identification (RFID) technology is a wireless communication technology, in which an RFID tag is attached to a surface of an article, and a customer identifies the article by reading an ID in the RFID tag through a device in a self-service transaction, and has the following disadvantages: the RFID electronic tag is high in cost, the unit price of a common RFID tag is about 0.2-0.5 yuan, for liquid and externally-packaged metal commodities, the RFID tag can lose effectiveness, if the problem that the RFID tag of the commodities fails is to be avoided, the RFID electronic tag with higher cost is required to be adopted, the existing RFID tag is not a commodity delivery standard, and enterprises need to invest a large amount of manpower to paste in the later period, so that the enterprise cost is increased;
4. no loss prevention: because the scheme can not well solve the loss prevention problem of self-service cash register, part of enterprises directly cancel loss prevention control, the commodity loss prevention pressure of the enterprises is multiplied, more manpower is required to be invested to monitor the customer transaction in a self-service area, and the purposes of reducing personnel and increasing efficiency of the enterprises and saving cost can not be achieved.
Therefore, the invention provides a self-service cash-receiving AI loss prevention system and method based on hand track recognition, aiming at the problems.

The embodiment is that the action of customer's hand is reasonable, is the motion track of keeping in goods earlier, sweeping the sign indicating number again, back bagging-off, but the sign indicating number failure is swept to bar code scanning module, but the condition that customer did not discover, in time gives customer's warning, prevents that the goods from sweeping the sign indicating number failure customer by mistake and not sweeping the loss that sign indicating number goods brought and customer's awkward experience for the trade company.
Example 3
The embodiment provides a self-service cash-receiving AI loss prevention method based on hand track identification, which specifically comprises the following steps:
step 1: a customer takes the commodity from the temporary storage area or the unknown area and directly puts the commodity into the bagging area, and the barcode scanning module does not collect the commodity barcode;
step 2: the video acquisition module acquires dynamic image data in the transaction process of a customer and sends the dynamic image data to the server;
step 3.1: the server tracks hand movement, form and movement track in the dynamic image data;
step 3.2: judging that the commodity is held in the hand, and carrying out the next step;
step 3.3: performing abnormal behavior analysis, judging that the operation is a behavior which does not conform to a preset action track and belongs to an illegal behavior, and judging that the analysis result is abnormal;
step 3.4: sending the analysis result to a self-service cash register terminal and a mobile terminal;
and 4, step 4: and if the analysis results received by the self-service cash register terminal and the mobile terminal are abnormal, directly alarming and freezing the transaction, and manually intervening whether to scan codes again or to finish the transaction.
The embodiment is that the customer directly takes into the condition in bagging-off district with commodity from the region outside the workstation, in time discovers some lawless persons, and in time reports to the police, prevents lawless persons, for trade company's loss stopping.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
